An arbitrary point is removed from a three-dimensional Euclidean space on a two-dimensional sphere. The new well-posed solvable boundary value problems for the corresponding Laplace–Beltrami operator on the resulting punctured sphere are presented. To formulate the well-posed problems, some properties of Green’s function of the Laplace–Beltrami operator on a two-dimensional sphere are previously studied in detail.
Keywords: Laplace–Beltrami operator, two-dimensional punctured sphere, well-posed problems, Green’s functions, elliptic equations.
